Data Engineer Fellow

As a Data Engineer Fellow, you will support the development and maintenance of NHHRI's cloud-based population health data warehouse by designing scalable schemas, integrating public-sector datasets, and ensuring data quality and reliability.

NHHRI seeks a Data Engineer Fellow to design and implement relational structures within the organization's BigQuery environment. The Fellow will standardize, clean, and integrate federal and state datasets into a governed warehouse framework, supporting board reporting, research analysis, and future AI-enabled analytics.

This role focuses on building the structured data foundation that enables visualization, research, and strategic decision-making., *

• Design and implement scalable relational schemas in BigQuery
• Develop and maintain core reference tables (e.g., dim_geography, dim_time)
• Build and maintain standardized fact tables for integrated indicators
• Load, clean, and standardize federal and state datasets
• Harmonize mixed geographic levels (state, county, tract, ZIP as applicable)
• Transform datasets into consistent long-format structures where appropriate
• Write validation and quality-control SQL queries
• Optimize tables using partitioning and clustering strategies
• Monitor query efficiency and usage
• Maintain organized raw, staging, and curated data structures
• Document schema design decisions and transformation logic
• Support reproducibility and governance standards
• Collaborate with Visualization and Research Fellows to ensure consistent metric definitions.

• NOTE: It's an unpaid fellowship.

Do you have experience in Query management?, Do you have a Bachelor's degree?, + Bachelor's degree (completed or in progress) in Computer Science, Data Science, Information Systems, Statistics, or related field

• Demonstrated proficiency in SQL, including joins, aggregations, and table creation (DDL)
• Experience working with structured datasets (CSV, Excel, relational tables)
• Experience cleaning, transforming, and standardizing data
• Basic proficiency in Python (or similar scripting language) for data processing
• Familiarity with geographic identifiers (e.g., FIPS, GEOID) or demonstrated ability to work with geographic data structures
• Strong analytical and problem-solving skills
• Ability to document data transformations and assumptions clearly
• Ability to work independently and meet defined project milestones

Preferred Qualifications: *

• Experience working with cloud data warehouses e.g., BigQuery.
• Experience designing relational schemas or dimensional models (e.g., fact and dimension tables)
• Experience integrating public-sector datasets (e.g., Census, CDC, CMS, BLS)
• Experience building or supporting ETL/ELT workflows
• Familiarity with data governance concepts (metadata, lineage, documentation practices)
• Exposure to AI/ML concepts or interest in applying AI techniques to structured population health datasets
• Experience using AI-assisted data tools for cleaning or query generation
• Interest in contributing to AI-enabled analytics built on top of structured data foundations, The ideal candidate demonstrates strong SQL proficiency and practical experience designing scalable relational schemas within a cloud-based data warehouse environment. They possess the ability to clean, standardize, and integrate structured public datasets across mixed geographies and time dimensions. The Fellow is detail-oriented, execution-driven, and capable of building reliable, well-documented data structures that support visualization, research analysis, and future AI-enabled analytics aligned with NHHRI's long-term objectives.
